[0024] Please refer specifically to Figures 1-4, A chain saw end cap, including a main body cover 1 and a central positioning block 2. An opening groove 11 is provided on the main body cover 1, and the central positioning block 2 is installed in the opening groove 11. The opening groove 11 penetrates through one side of the main body cover 1. Six clamping parts 12 are arranged along the outer periphery of the opening groove 11 on the main body cover 1. A clamping groove 13 is arranged inside the clamping part 12. Six convex blocks 21 are arranged on the outer periphery of the central positioning block 2. The convex blocks 21 are adapted to the clamping grooves 13, and the convex blocks 21 can be clamped into the clamping grooves 13 to form a clamping fixation. A first anti-retreat part 14 is arranged outside the clamping groove 13, and a second anti-retreat part 22 is arranged at the bottom of the convex block 21. The first anti-retreat part 14 is adapted to the second anti-retreat part 22. After the convex block 21 is installed in place, the first anti-retreat part 14 abuts against the second anti-retreat part 22 to prevent the convex block 21 from separating from the clamping groove 13, so that the main body cover 1 and the central positioning block 2 can be well clamped and fixed together. One end of the main body cover 1 is an arc head 15, and two symmetrically distributed arc-shaped clamping protrusions 16 are arranged on the arc head 15. The clamping protrusions 16 are adapted to the clamping protrusion grooves on the chain saw. Six symmetrically distributed positioning holes 17 are arranged along the outer periphery of the main body cover 1. The positioning holes 17 are adapted to the convex columns on the chain saw. Multiple positioning notches 23 are arranged on the central positioning block 2. The positioning notches 23 are adapted to the plugs on the chain saw. Aligning the clamping protrusions 16 with the clamping protrusion grooves, the positioning holes 17 with the convex columns, and the positioning notches 23 with the plugs makes the connection between the end cap and the chain saw more convenient.

[0025] In this embodiment, the main body cover 1 is made of recyclable PPGF30 material. By using recyclable PPGF30 material, while reducing the production cost, the strength of the main body cover 1 is ensured, and at the same time, environmental pollution is avoided. The central positioning block 2 is made of aluminum alloy. That is, the chain saw end cap of this application is composed of a plastic main body cover 1 and a metal central positioning block 2, which reduces the production cost while ensuring the original strength.

[0026] Pressing grooves 18 are arranged on both sides of the opening groove 11 of the main body cover 1, and pressing clasps 24 are arranged on both sides of the central positioning block 2. The pressing clasps 24 are adapted to the pressing grooves 18, ensuring the combination of the main body cover 1 and the central positioning block 2.

[0027] An alignment groove 19 is arranged inside the opening groove 11 of the main body cover 1. The clamping parts 12 are arranged on both sides of the alignment groove 19. One end of the central positioning block 2 is provided with an alignment block 25. The convex blocks 21 are arranged on both sides of the alignment block 25. The alignment block 25 is adapted to the alignment groove 19. The alignment block 25 and the alignment groove 19 play an alignment role. When assembling the main body cover 1 and the central positioning block 2, as long as the alignment of the alignment block 25 and the alignment groove 19 is ensured, it can be ensured that the convex blocks 21 can be clamped into the clamping grooves 13.

[0028] The clamping parts 12 and the clamping grooves 13 are in the shape of isosceles trapezoids; the convex blocks 21 are also in the shape of isosceles trapezoids. The isosceles trapezoid design makes it more difficult for the convex blocks 21 and the clamping grooves 13 to separate.

[0029] There are two through holes 26 provided on the central positioning block 2, and the centers of the two through holes 26 are on the same straight line. The through holes 26 play a role in positioning and locking, that is, the chain saw end cover can be fixed to the outside of the chain saw through fasteners, thereby protecting the internal mechanical and electronic components and extending the service life of the chain saw.

[0030] The present utility model is a chain saw end cover, and its working principle is described in conjunction with the accompanying drawings:

[0031] The main body cover 1 and the central positioning block 2 are made by different molds. Since the main body cover 1 is made of plastic, the opening groove 11 can be slightly opened to facilitate the installation of the central positioning block 2. Align the alignment block 25 of the central positioning block 2 with the alignment groove 19 of the main body cover 1, and install the central positioning block 2 into the opening groove 11. It is fixed in the main body cover 1 through the snap-fit of the convex block 21 and the card slot 13 and the snap-fit of the press-fastening buckle 24 and the press-fastening groove 18. Under the action of the first anti-withdrawal portion 14 and the second anti-withdrawal portion 22, the central positioning block 2 will not easily fall out of the main body cover 1. After the main body cover 1 and the central positioning block 2 are assembled, align the card convex 16, the positioning hole 17 and the positioning notch 23 with the corresponding parts on the chain saw (not shown in the figure), and then fix the chain saw end cover by installing fasteners in the through holes 26. The chain saw end cover can prevent external substances, such as dust, wood chips, water, etc., from entering the chain saw interior, thereby protecting the internal mechanical and electronic components and extending the service life of the chain saw; at the same time, it can also increase the overall aesthetics of the chain saw and reduce the noise generated during the operation of the chain saw through its design.
